High-flying aircraft release NO Into the stratosphere, which catalyzes this process. When O3 and NO concentrations are 5 x 10^12 molecule/cm 3 and 2 x 10^9 molecule/cm3, respectively, what is the rate of O3 depletion? The rate constant k for the rate-determining step Is 6 times 10-15 (cm3) 2/molecules. Give your answer in scientific notation

Samantha · Answer 1

1) NO + O3 - > NO2 + O2 (slow)

2) NO2 + O - > NO + O2 (fast)

Overall reaction: O3 + O - > 2O2

1) rate = k [NO] [O3]; slow, rate determining step,

k = 6 x 10^-15 (cm^6/molecule
